So, I was given a 88 or 89 Schwinn World Sport last summer and I'm finally getting around to fixing it up. So far, I've kept the original 27 x 1 1/4" rims and put new tubes and Schwalbe white wall tires on them. Next step is a trip to the local bike shop to get them trued. I also changed the old bulky front and back brakes to Shimano Sora caliper brakes, so now I have the quick release, which is nice. I got some new brake cables and housing to put on as well. So, one question is; while putting in the brake cables, do you think it's a good thing to have a cable stretcher? I'll be changing all the gear cables soon too, so maybe it's a good investment? Also, any other opinions about adding lubricant inside the brake housings? And would you put lubricant in gear cable housings? I haven't looked into that yet. Then, when that's all said and done - new seat and seat post, a tune up and it'll be ready to ride!! Thanks!
